17track not providing package details

I’ve used the 17track integration for a while. After the last HA 5.0 update I noted I no longer saw package details on my dashboard cards. I’ve removed and re-added the integration. I see the correct number of packages in each sensor, but no way to get individual package data from these any longer.

I don’t see an attribute called “packages” in the sensor data when I check its state in the Developer tools (as in the image above) so the template card provided in the integration documentation fails to render.

Is anyone currently using this integration successfully? It’s been great in the past but I’m not sure how to adapt it now.
